From what I can see here - http://mapofcoins.com/bitcoin - I0C is a clone of IXC, which is a fork of BTC.. So how can a clone of a fork of BTC be the "root" of all BTCs?

And in case I0C and IXC is essentially the same, shouldn't it still be IXC that is the real "root", since it's the fork and not just a clone of a fork?

And then again.. How can a fork of BTC be more real than BTC? What about the pre-IXC era then?

Not a programmer, so would be nice íf some of you could give me some answers.
